Aligning Metabolic Pathways Exploiting Binary Relation of Reactions. [PDF]

open access: yesPLoS ONE, 2016
Metabolic pathway alignment has been widely used to find one-to-one and/or one-to-many reaction mappings to identify the alternative pathways that have similar functions through different sets of reactions, which has important applications in ...

Decision Analysis via Granulation Based on General Binary Relation [PDF]

open access: goldInternational Journal of Mathematics and Mathematical Sciences, 2007
Decision theory considers how best to make decisions in the light of uncertainty about data. There are several methodologies that may be used to determine the best decision.

Fixed point results via altering distance functions in relational fuzzy metric spaces with application [PDF]

open access: yesMathematica Moravica, 2021
Some fixed point theorems are developed in fuzzy metric spaces using an altering distance function under binary relationship. We ensure the existence and uniqueness of the solution to ordinary differential equation using our results.

$\mathcal F$-hypercyclic and disjoint $\mathcal F$-hypercyclic properties of binary relations over topological spaces [PDF]

open access: yesMathematica Bohemica, 2020
We examine various types of $\mathcal F$-hypercyclic ($\mathcal F$-topologically transitive) and disjoint $\mathcal F$-hypercyclic (disjoint $\mathcal F$-topologically transitive) properties of binary relations over topological spaces.

Perov-fixed point theorems on a metric space equipped with ordered theoretic relation

open access: yesAIMS Mathematics, 2022
In this paper, we introduce a few new generalizations of the classical Perov-fixed point theorem for single-valued and multi-valued mappings in a complete generalized metric space endowed with a binary relation.

The Stability and Well-Posedness of Fixed Points for Relation-Theoretic Multi-Valued Maps

open access: yesMathematics, 2023
The purpose of this study is to present fixed-point results for Suzuki-type multi-valued maps using relation theory. We examine a range of implications that arise from our primary discovery.

New Relation-Theoretic Fixed Point Theorems in Fuzzy Metric Spaces with an Application to Fractional Differential Equations

open access: yesAxioms, 2022
In this paper, we introduce the notion of fuzzy R−ψ−contractive mappings and prove some relevant results on the existence and uniqueness of fixed points for this type of mappings in the setting of non-Archimedean fuzzy metric spaces. Several illustrative

A Relation-Theoretic Metrical Fixed Point Theorem for Rational Type Contraction Mapping with an Application

open access: yesAxioms, 2021
In this article, we discuss the relation theoretic aspect of rational type contractive mapping to obtain fixed point results in a complete metric space under arbitrary binary relation.

Remarks on “Perov Fixed-Point Results on F-Contraction Mappings Equipped with Binary Relation”

open access: yesAxioms, 2023
Since 1964, when I.A. Perov introduced the so-called generalized metric space where d(x,y) is an element of the vector space Rm, many researchers have considered various contractive conditions in this type of space.

Binary and ternary relations [PDF]

open access: yesMathematica Bohemica, 1992
Let \(G\) be a set, \(\rho\) a binary relation on \(G\). Further, let \(r\) be a binary relation on the set \(\rho\) with the property \(\alpha=(x,y)\in\rho\), \(\beta=(z,u)\in\rho\), \((\alpha,\beta)\in r\Rightarrow y=z\). Then \(r\) is called a binding relation on \(\rho\), and \((G,\rho,r)\) is called a double binary structure.
